Answer:

(x -a)^2 + y^2 = 2a^2

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

Here r^2 is the square of the distance between the center and the point on the circle. That can be found using the distance formula:

d^2 = r^2 = (x2-x1)^2 +(y2 -y1)^2 = (0-a)^2 +(-a-0)^2 = 2a^2

Filling in the above formula with (h, k) = (a, 0) and r^2 = 2a^2, we find the equation to be ...

(x -a)^2 +y^2 = 2a^2

What does <br> f(x) – g(x) =

andrezito [222]

Answer:

(f - g) (x)

Step-by-step explanation:

Since (x) is common between them, you can bring it out. for example,

f(x) = x +1

g(x) = 2x + 3

f(x) - g(x) = x + 1 - 2x + 3

= -x + 4

(f - g) (x) = x + 1 - 2x + 3

= -x + 4

How many possible combinations of 4 numbers 1-9?

beks73 [17]

1. There are 10, 000 combinations, you have 10 choices for the four digit and there are 10 x 10 x 10 x 10 which is 4-digit combination from 1-9. This is called combinations; the calculation comes out to 10^4.

I want to learn how to solve a slope problem

mina [271]

The slope (or average rate of change) formula is: $m= \frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }$ . It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as $( x_{1}, y_{1})$ and the other as $( x_{2}, y_{2})$ . Then you insert these points into the slope formula (m represents slope). So, $m= \frac{6-1}{-3-5}$ where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to $m= \frac{5}{-8}$ .
